   产品概述 返回TOPHQD嘉泰姆

The CXLE8861 is a step-up DC/DC converter with a constant current to drive white LEDs or similar. The device can drive up to eight LEDs in series from a Li-Ion cell. The LED current is set by the external resistor (RSET) and is directly regulated by the feedback (FB) voltage (typ: 200 mV) across the external resistor RSET. To ensure maximum safety during operation, the output has integrated overvoltage protection that prevents damage to the device in case of some fault conditions. The OVP voltage can be programmed by two external resistors. 

The CXLE8861 is available in a tiny DFN3*3-8L package.
